apparently 36 isotopes, from Cu52 to Cu80. with half-lives ranging from just 75ns, to 61 hours.
however most of your everyday copper is made of the two stable isotopes Cu63 and Cu65.

Numerous (I think there are 31), but only two really stable ones, Cu-63 and Cu-65; the rest are unstable isotopes with short half-lives, some only a few minutes, most less than a second.

Isotopes of copper iso NA half-life DM DE (MeV) DP
-63Cu 69.17% Cu is stable with 34 neutrons
-65Cu 30.83% Cu is stable with 36 neutrons
(there are two)

Here's a list of them all. Some have half lives in the nanosecond range
